Hi guys,
My GNex has a problem. Many users seem to have a similar problem but theirs seem to be hardware related and I'm pretty confident mine is software related.
It started a few months ago when my GNex wouldn't charge through the wall charger. I was on a trip with my friends so I didn't have access to a pc and wasn't able to troubleshoot further. The charging icon would appear when the phone was off but when I turned it on it didn't charge. I played around with the phone for about two hours, rebooting, Googling for solutions, changing the USB connection modes in the Storage settings. When I changed from Next Launcher to Stock launcher and rebooted everything was working fine again. However I think it was only a coincidence. Then the problem didn't occur again until now and this is why I think it's software related. If hardware would have been broken the problem wouldn't just have fixed itself like that.
It happened 3 days ago but somehow fixed itself again. I was troubleshooting the issue with my GNex connected to PC and installed Nexus Root Toolkit by Wugfresh. During install my phone rebooted on it's own and suddenly USB worked perfectly again!
However yesterday I forgot to charge and my GNex died. On reboot the issue was back.
"Symptoms":
Phone won't charge with any wall charger (and any cable) unless off
Phone will charge through USB in any mode but PC will not recognize it and install it as unknown device.
USB Debug Icon and Connection Mode notification do not appear in status bar upon PC connection
OTG doesn't work and apps like "Stickmount" do not detect external drives
Attempts:
Gently bending the "tongue" inside the micro usb on the phone in case there is a bad connection
Reinstalling drivers on PC
Rebooting device in different modes including fastboot
Using different batteries
NOTES
This problem started after latest 4.3 update. It has only occured after battery completely runs dry. I have 3 batteries (a bit excessive I know) and an external battery charger so charge is not the issue, I just really want to understand what's going on with my phone.
I'm not ready to Factory Reset or replace the USB port yet, those are last resort options to me. Any other options, especially software related, are very welcome. I am on stock 4.3 only rooted and with CWM recovery.
In Testing menu (type *#*#4636#*#* in Dialer) under Battery Settings my phone also says Charging (AC) when connected through USB. Hope this helps.
Been Googling around for two days now so I decided to make my own thread. Any help is appreciated. Sorry for this very long post.
Fixed it! Tried bending the tongue inside the micro usb again, forced much more this time, everything is working again, for the moment
Before last week I never rooted the device Nexus 7 2013(WiFi) or did any other modification.
Last Friday I decided to root the device using towelroot(used it on my Nexus 5 as well) in order to download and install Android 5.0 using an app from the Play Store (I forgot the name it had a nexus logo and it downloaded OTA Image and installed it).
Up until an hour ago everything was fine and the device had 42% of Battery, 10 minutes after the last time I used the device I tried to wake it and the screen just didn't turn on(still won't).
I know the device is on because when I plug it in the USB the computer does the sound of a connected device.
Could anyone please help me solve the problem?

Do you get the charging icon when you plug into the OEM Charger, or nothing at all?
You might have a failure on the board. I had the same issue, and would get a weird driver when I plugged into my computer. I was still in the warranty period, so I RMA'ed, however, if you are not, folks have had luck with opening the tablet, disconnecting the battery, and then reconnecting.

Unfortunately nothing at all and I am after the warranty period,
Could you maybe recommend me a guide on how to open the tablet and disconnecting/reconnecting the battery?
Ok, first off I chose Sprint because I believe that Boost Mobile is on the sprint network, but my phone doesn't specifically say sprint on it or anything, so I had no clue which of these device boards to post into. This is the exact page I got it on, if that helps. [link deleted - paranoid forum rules] - I will post specs of the device in a minute.
Alright, the issue with my phone, is that after I used a car charger 2 months after I got my phone, it suddenly stopped being able to connect to ANY computer ever again. I suspected it was PDA net at first cause that was the newest change I had done to my phone. So, a few days later, I could find now way whatsoever to fix it, and had to factory reset. This fixed my phone just fine.
Two months later, I was fed up with having battery issues all the time, this phone drains battery faster than my laptop, and its battery is 3.8 years old! I got an external battery that holds 20,000 mAh/74 Wh (Practically the same as my laptop battery too. ) that is from the LimeFuel company. I know that before I used it, my phone worked with my laptop just fine. I don't plug my phone in to my laptop all that often, especially now that I have a battery to use with it. However, I download large files on my phone with 4G to put onto my laptop because my home net is crappy, so a week after, I noticed that my phone lost the ability to communicate with computers, again. I then realized, it had to be the connections. The first time it happened was when I used a car charger, the second time, an external battery. Each time, my phone suddenly inexplicably lost the ability to communicate with a computer ever again. It can only see devices as a power source, nothing more. There's no missing software or drivers, it just doesn't register as anything to my computer. Like a power toggle so it can't tell the computer "Hey, I'm a device that you can transfer data with".
One more note; The first time this happened, I had activated developer options but had them turned off. I mean that I used USB Debugging mode once and turned all of that off. The second time, I hadn't even unhid the option yet, unhid after my phone broke again to try and fix but nope.
I did research on trying to fix it, without factory reset because a factory reset is USELESS, if it's going to happen every single time I use anything but the wall to charge it, right?
There was a topic online claiming that there is a menu under "Storage" in the settings. There isn't. It was a big fat lie. Or Android devs deleted it.
There was another topic, claiming that USB settings would be under some wireless and networks area. Nope.
Now, I remember that when my device would connect to the computer, it would let me change it from MTP to PTP, but after this happened, nothing. It doesn't even pop up anymore, nor does it ask. There is no where in the phone that these options even exist at all. It's like Android devs deleted access to these options for no reason whatsoever.
Another bit in that topic mentioned ‘USB Mass Storage’, which also doesn't exist. Here's the topic with everything I tried, if I'm allowed to give links at all. If not, well not my fault. Topics used to try and diagnose and fix issues, but failed;

Why does it stop accepting data from computers after I use a car charger or an external battery pack?

First off, after the factory reset and everything worked did you reinstall the pdanet?
Second, 20,000mah battery? Holy cow im jealous!
Forgive me if you have already tried these things but this is what i would do...
Did you reenable developer options and reenable adb debugging?
Did you uninstall and reinstall your phone drivers?
Is there an updated phone driver?
Have you tried a different usb cord?
Is there excess dirt or dust in usb charge port on your phone?
Does your usb charge port even work anymore or do you just charge external battery on wall?
Have you tried a different usb port on the computer?
Have you tried on another computer?
Have you tried updating computer drivers?
Have you enabled a fast charge tweak like on a kernel tweak app?
If none of these questions fix it then a workaround is downloading app called airdroid. You can wirelessly transfer files from phone to computer and back again without usb cord.
Let me know what worked please! Good luck!

1. No, I never touched PDA net again.
2. Too bad forum rules say I can't be friendly and give you the link to it.
3. Read the topic you quoted. I did, only after my phone broke again. Except it's not adb debugging, it's USB debugging. Doesn't work, because the phone can't communicate with a computer anymore.
4. 5. 11. Yes I reinstalled drivers and no there were no updates.
6. 7. Nothing's wrong with the cable. I did try with others.
8. What does that even mean? Yes my phone's port works. Nothing's wrong with any hardware.
9. 10. I've tried different ports and different computers.
12. Can't, phone isn't rooted.
13. I'm not using this. My phone is not there for Google/Android to tell me I'm not allowed to use my USB port ever again. I'm also not going to wait 4 hours for a 4 GB file to transfer via my router to my computer nor am I installing some app software to my computer just to have wireless transfer. This is not a work around. This is an "Oh well, it's broken, guess you can't ever use USB ports again for data access!"
note; I tried all of these (except 12/13) before I ever came here looking for help.
2. I will google it
3. I didnt realize toggle to turn on usb debugging didnt work sorry. I just know it needs to be on for the computer to see the phone. This seems to be an area of problem possibly.
8. Lol! What i meant was did the area where u insert charger function properly. Only reason i asked is because some of those batteries charge on wall unit made specifically to charge the battery only not with charge.
12. Doesnt require root for basic settings like changing governor usually. Only to overclock/undervolt, etc.
13. Great answer! But i meant as a temporary fix until someone more experienced with this issue helps you.
I also figured listing all those things would help other people see what you had and hadnt tried before asking you next time. Wish i couldve helped more. Good luck

2. amazon dot com /External-20000mAh-Limefuel-LP200X-Flashlight/dp/B00OHZVN5U/ - It let me charge my phone 7-8 times fully before it was empty. Automatically stops when your phone is full.
3. USB debugging doesn't need to be on in order for a phone to communicate with a computer. This is only if you want to debug apps or use other developer tools. File transfer works just fine without it.
8. I still don't understand what you mean. My phone is not broken in any way. Nor is my battery. My external battery charges off any USB input, my phone charges off any USB input. My phone just can't communicate data wise between devices anymore via USB.
12. Fast charge isn't going to fix my phone. Unless it disables data communication, then I need to turn it off. All "kernal tweak apps" appear to require root. The top 5 google searches shown this.
3. Wasnt sure. Ive always had it on
8. Some aftermarket batteries dont charge while in phone hooked up to charger. They come out of phone and into specialized charger for battery only not phone with it, so that it can charge the larger battery in a matter ofan hour or so is what i have been trying to say. But its obvious thats not the case for you now since i asked and clarified. If this was the case one might not know that the small usb port on their phone needed cleaning to make a good connection because they literally dont use it to charge their phone. They charge their phone with external battery charger. You see?
12. On my custom rom and on my trickstermod app it does say fast charge disables data communication and that you have to turn it off for computer to recognize phone again. This fast charge mode only works when connected to computer not wall charger it says
Wish i could be more help but im out of ideas. Good luck
Update to the current situation.
My phone is somehow, repaired. But I have no clue why. I did several things today, just screwing around while I backed up my stuff to the SD card. One of them could have fixed it, or my phone is magic and self repairs after a while. Lets list everything I can remember that I did.
1. I typed in *#9900# in my dialing app. Toggled an option called "Low battery dump" to "on".
2. I deleted a whole bunch of files, including hidden files on the internal storage. Probably screwed up my apps but, whatever, it works now.
3. I pulled the SD card out.
Shortly after all these things, I plugged it in for power, and it finally, got my computer to see it as an MTP device again. No clue which of these succeeded. I'm going to wait a small bit before I test the things that tend to break it.
The magic option, is because I tried to root, it broke, stuck in download mode with some error about firmware. For 4 hours it was stuck like this, I tried everything I could think of, which wasn't much, tried installing the ROM back too, after wasting 2 gigs of bandwidth downloading it only to get an error before it even started the install. Phone was still rebooting in download mode error screen. Left it sit there off for like a minute and it just turns it's self back on, flickers a few times and the logo pops up and the device pops on like nothing had ever happened to it. I'm so confused. :/ At least everything's back to normal. Now add a good confusion post icon below so I can click it and post. :|

Except, I don't have a fast charge option anywhere. I can't toggle fast charge. My phone is unrooted and locked and such. If plugging in a device like a battery or a car charger, toggles this option and the OS developers deleted access to toggle this option, it is an OS bug and a critical issue in the device that needs to be fixed. I don't know what fixed it, but I'm assuming it was the low battery dump, and that doesn't appear to have anything to do with fast charge and it was a hidden secret option in the system.

The way u said it i misunderstood i thought u did have it on. Its not an option on all roms though. Mine has it and i tried it and couldnt see files thru usb until i toggled it off so it was just an idea. I dont know the effects of the low battery dump off top of my head but i will remember that if i hear someone else with same problem. Glad its fixed now
I just tried to install the pie update manually by downloading the zipped update, renaming it and placing it in the root and dialing the code. The installer started and took about 10 minutes to complete and asked to reboot at the end. Now after the reboot the phone shows absolutely no signs of life anymore.
The phone soesn't turn on, doesn't respond when i connect the charger (it doesn't even get warm) and nothing happens when i try to connect it to my pc. Did i mess something up? Does anyone know a way to bring it back to life?

This happened to me after a day of updating to pie.
I noticed that my phone is charging very slowly.I used ampere app from play store to measure the current...and found that current coming through charger is too low(about 100 milli amphour) and i thought it might be my charger fault.
Then i used another charger and got same result....i was totally shocked.!!
I don't know if it is a software problem or hardware.
So today i'm giving my device to Nokia service center......and lets see what exactly the problem is..
I think this is my last Nokia device....i'm completely dissapointed by Nokia!!
BTW...i didn't do it manually i got an ota update.
Hi,
this probably will not help much, think i have the same issue.
i have had my ta-1050 get stuck on bootloader? ~3 times now over maybe 6 months of ownership, the last time was my update this weekend to Pie.
rather frustrating .
Can see the device is stuck in bootloader when i plug the handset in to my windows computer\device manager, can see and under com ports the is a QDloader 8006.
then need to wait ~2days for the battery to go completely flat, then plug into fast charger and it boots up again.
if take device to nokia, pretty sure i will get no fault found by the time they look at it.
